Getting Around
By ferry: Atlanticoline sails between all 9 islands, but we only really recommend ferries within the central island group of Terceira, Sao Jorge, Pico and Faial as these routes are shorter (1-2 hours, or only 30 mins from Faial to Pico), year-round, and less liable to weather disruption. The longer routes tend to tun only from May-September, and can take anything from 4 hours to overnight - so we advise flying these routes (see above).
On each island: you'll almost certainly want to hire a car in order to explore freely: they are not expensive (standard European prices), but stock is limited (and ageing) so you should book well ahead for summer dates. Otherwise, if you're staying somewhere central such as Ponta Delgada, you could use minibus tours, which are widely available and generally well run.
